Been using an Amiga 1200 for the past 15 years with a blizzard PPC 603e 250 mhz, and a 68040 35 mhz, never had it recapped, and it works very well. One thing though is if you are going to use this card in a keyboard case do like I done, I raised the Amiga off the desk by using some 3/4 inch nuts hot glued to the bottom to raise it up and get the darned heat sink off the desk. this gives about 1/8 to 1/4 inch clearance and cuts down on heat problems. Maybe one of these days when I get off my lazy butt, I will take a picture of it. Still like the 040 better then an 030.
